For the Multi system air conditioner unit, one outdoor unit
is able to drive up to
four or five indoor units which can be cassette type, duct type,
wall-mounted
or

Among
them,
the
cassette
type
and
the
wall-mounted
indoor

should
be
controlled
by
the
remote

while
the
ducted type can be controlled by either the remote controller or the wired controller. The
outdoor unit will run as long as any one indoor unit receives the running command, and
all indoor units stop once the outdoor unit is turned off.
